Hello Malgo,
At first sight I thought it was a park, So when I found out that you took it inside the metro, I was surprised to find such a pleasant atmosphere inside a crowdy place which aldso moves so much. Good idea to convert in BW . I would certainly enjoy to have taken it myseld and show it around.

Hello,
Although the picture seems attractive at first glance, I think that there are some tactical mistakes in the graphism. I believe that there are two ways of shooting architecture: Either We respect the verticals and shoot the building as it looks or we raise the camera with a particular angle and then the shape changes completely. But sometimes the photographer can find an attractive angle and we may also like this kind of dynamic result. But what I am not sure of is the fact that in this particular case you have chosen symmetry which does not really look symmetrical. I would have preferred a deliberate raising of the camera and a better control of the two sides .
